New UK-wide vaping laws come into effect on Monday May 20, bringing with them a raft of new rules and regulations.

The new Tobacco and Related Products Regulations 2016 will mean changes to the way that e-cigarettes and e-liquids are sold across the country.

They will also introduce new punishments for those who do not comply with the legislation, including up to two years in prison and/or an unlimited fine.

The May 20 changes state:

• All e-cigarettes and e-liquids must be registered with the Medicines and Healthcare products Regulatory Agency before they can be sold

• Refillable tanks for e-cigarettes must be no bigger than 2ml capacity

• E-liquids cannot be sold in quantities greater than 10ml

• Unless registered as a medicine the strength of nicotine in an E-liquid must not exceed 20mg/ml

• The packaging of E-liquids must be child-resistant and tamper evident

• Certain additives such as the stimulants caffeine and taurine or colourings are banned

• New labelling requirements

The changes in law apply to anyone who makes or sells e-cigarettes and e-liquids - including those who sell online via social media, auction sites or from their own website.

And, after being contacted by the Plymouth Herald, Trading Standards have said that they are particularly keen to get the message out to people who brew e-liquids at home to sell online as these are the most difficult business to reach.

Trading Standards manager Alex Fry said: “We are finding that shops are aware of the changes to the law but small online retailers are not.

“We have found online sellers selling e-liquids in 100ml bottles with a nicotine strength over 20mg/ml. After 20 May this will be illegal unless the e-liquid is registered as a medicine.”
